Every now and then we make advice for an unusual project. For example, we recently made a construction calculation for the roof floors of 44 life-resistant homes in Zwijndrecht. Moss sedum is applied to this and testing of this addition of load with a control calculation is necessary. This means that we calculated the existing concrete roof floors, whereby we tested whether the existing reinforcement is sufficient. We also tested the foundation of the houses for this greater load.

We approved both the foundation and the roofs!
